'''Grape phylloxera''' (''Daktulosphaira vitifoliae'' (Fitch 1855); family [[Phylloxeridae]]); originally described in France as ''Phylloxera vastatrix''; equated to the previously described ''Daktulosphaira vitifoliae'', ''Phylloxera vitifoliae''; commonly just called '''phylloxera''' ({{IPAc-en|pron|f|ɪ|ˈ|l|ɒ|k|s|ə|r|ə|}}; from [[Greek language|Greek]] φύλλον, leaf, and ξερόν, dry) is a pest of commercial [[Vitis|grapevine]]s worldwide, originally native to eastern [[North America]]. These almost microscopic, pale yellow sap-sucking [[insect]]s, related to [[aphid]]s, feed on the roots and leaves of grapevines (depending on the phylloxera genetic strain). On ''[[Vitis vinifera L.]]'', the resulting deformations on roots ("nodosities" and "tuberosities") and secondary fungal infections can [[Girdling|girdle]] roots, gradually cutting off the flow of nutrients and water to the vine. [[Nymph (biology)|Nymphs]] also form protective [[gall]]s on the undersides of grapevine leaves of some ''Vitis'' species and overwinter under the bark or on the vine roots; these leaf galls are typically only found on the leaves of American vines.
